Flat Bar Attachment 1

A flat bar attachment is used when a low overall height is required, usually when the attachment is to be capped. Flat bar is also used to go around curves. Layfield normally uses an angle bar attachment for most work. Flat bar does not provide sufficient stiffness to make a permanent compression seal. Sponge neoprene gaskets, often specified with flat bar, do not normally provide long term compression. Usually only 50 to 60 durometer neoprene gaskets should be used. Flat bar is attached at 150 mm (6") centers which normally costs more than the 300 mm (12") centers required for angle bar.

Liners are attached to clean, smooth concrete, using wedge anchors drilled into place. These wedge anchors are best placed during liner installation as it is very difficult to keep the concrete surface clean and smooth with cast-in-place anchors. The most difficult aspect of attaching liners to concrete is to obtain a smooth, clean surface.
